Why?

Strongest counted support: The primary study describes Bianfu Cave’s Denisovan locality status relative to Denisova Cave. weight 1.800000 evidence

Suppressed as dependent: The quoted passage directly identifies Bianfu Cave as a Denisovan locality with the most abundant remains outside Siberia’s Denisova Cave.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Unresolved.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

Under neighbouring settings of the same model: 0.7790 to 0.9121, a spread of 0.1331.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Primary archaeological conclusion.
The quoted passage directly identifies Bianfu Cave as a Denisovan locality with the most abundant remains outside Siberia’s Denisova Cave.

From Ancient proteins identify various Denisovan remains from Southwest China Read 2026-09-29 Relevance DIRECT Steps 0 Counted

The excerpt matches the locality and comparative-abundance claim.

Evidence against

None.

Qualifications

The study screened over 60,000 fragments and selected 76 for ZooMS and 17 for proteomic sequencing.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.
